克莱尔·邓菲（Claire Dunphy，朱丽·鲍温饰）催促家人赶快动身前去父亲杰伊·普里切特（Jay Pritchett，艾德·奥尼尔饰）家里给自己的“弟弟”曼尼（Manny，里克·罗德里格兹饰）庆祝生日，结果她和老公菲尔莫明其妙地就开始比赛看谁能先赶到目的地。于是夫妻俩分别开车上路，两个女儿亚历克斯（Alex，阿芮尔·温特饰）和海莉（Haley，萨拉·海蓝德饰）坐爸爸的车，小儿子卢克（Luke）坐妈妈的车。卢克在车上问克莱尔为啥要和爸爸“分开”，原来他把两人“分别开车”理解成了“分开”。然后克莱尔得知原来儿子想要坐爸爸的车，她感到有些生气，于是停下车来和卢克“理论”，结果越说越显得自己可悲。不过在卢克表示妈妈选的路线会比爸爸更快后，争强好胜的克莱尔马上就开心起来。菲尔则在车上试图说服两个女儿这样的比赛并不是浪费时间，结果车在路上抛锚了，修好车后，海莉和亚历克斯告诉爸爸她们都不想去参加那个聚会。菲尔居然难过得哭了起来，两个女儿慌了于是也跟着哭了起来。这样的插曲让菲尔失去了打败克莱尔的动力，不过最终女儿们还是成功说服他又鼓起了勇气。
与此同时，同性情侣米歇尔·普里切特（Mitchell Pritchett，杰西·泰勒·弗格森饰）和卡梅伦·塔克（Cameron Tucker，艾瑞克·斯通斯崔特饰）来到一家超市给曼尼选礼物。虽然米歇尔表示他们快要迟到，但卡梅伦还是停下来帮一位叫唐纳德的老人说服一位老妇人带他回家，他一开始很为自己的“善举”感到高兴，只是后来发现唐纳德和那位老妇人不是夫妻，而是在发展婚外情。卡梅伦和米歇尔开始进行争论，不过说着说着米歇尔突然加入到一群快闪族中跳舞，他本以为这可以给卡梅伦一个惊喜，但后者反倒觉得米歇尔故意把这样的事情瞒着自己而生气，之后到了车上两人又吵了起来。

The episode received overwhelmingly positive reviews from critics. Joel Keller of AOL's TV Squad called the episode "one of the better ones of the season". Despite this, he felt that the Mitch and Cam storyline while "funny" it was "not as funny as they usually are" He also commented that "It's just that sometimes Cam is too much Cam for his, or the audience's, own good." The A.V. Club's Donna Bowman gave the episode an A- rating. She felt "this episode is a bit less than the sum of its parts; or maybe the jigsaw pieces have been forced into place a little too emphatically."

James Poniewozik of Time gave the episode a positive review. He felt that "This episode may not quite have reached the level of "Fizbo", but by the time it built to its near-four-car-pileup, it had strung together quite a run of funny and sweet moments." HitFix writer Alan Sepinwall, who is often critical of the series's second season praised the episode commenting that "nearly everything was clicking". He also positively compared it to a season one episode of the series when "where everything came together at the end in the style of the strongest season one episodes ".
